Silverado door leak help

Probably not the door. Coming in behind the dash.

Yes I have

Open the hood and look way back by the firewall where the hood hinges are located on the body and that big black plastic cowling is located.

On the side of the cowling by the hinges right where the fender ends by the cab, run your hand down in that gap. There should be a flap on the side of that cowling that allows water to drain away from the windshield. That sometimes gets clogged with debris like leaves or that pollen crap oak trees drop and that will cause the water to back up and leak into the cab.

There is a drain on both the driver's and passenger's side of that plastic cowling.

Same problem - but Tundra. Two problems occuring simultaneously as described by both Hermit Crab and Gumbo.

Had windshield replaced and there was a small spot on passenger side not sealed properly - I discovered that when driving truck through a high pressure car wash and watched water pour though the spot not sealed. Windshield company fixed that ASAP and was very apologetic. Run your truck through a drive through car wash and check for leaks.

Next hard rain truck still still leaked, and the problem was a described by Gumbo. Easily fixed - clear those drains under the cowling near the door hinges. This problem is very common if you park your vehicle outside under trees while at home or at work, so now I routinely check and clear those drainage ports - and yes my truck is parked outside under trees most days.

Your post made walk outside and check the carpet in my truck following the very hard and intense rain early this morning - dry as a bone.

Do you have any play in the door? Can you lift up on it while open? Any movement? It’s the door pins.

Mine just started dripping on me last week on drivers side by emergency brake. Cleaned the debris out over the weekend and that seems to have resolved it.

My rear passenger pillar was leaking into the seat belt pulley.

Had to bring it in.
